SEWING-MACHINE ATTACHMENT.

Patented Feb. 11, 1908.

To all whom it may concern:

Be it known that I, BENJAMIN FLEIGEL, a

hand end View of the attachment; Fig. 4 a. I

section in the dotted line as, Fig. 1; Fig. 5

citizen of the United States, and aresident of I illustrates the work removed from the at- Chelsea, in the county of Suffolk and State of tachment after having been run through Massachusetts, haveinvented an Improvement in Sewing-Machine Attachments, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the production of a novel sewing machine attachment to be used in connection with sewing machines for guiding braid, tape, piping, welt,-etc.

In accordance with my invention the attachment is provided with a vertically adjustable tubular guide-way through which is led to the material the braid, tape, piping, welt or cord to be stitched in place by the usual needle of the sewing machine to the work-support of which the attachment is secured.

In many clas es of work done by a sewing machine attachment it is most desirable to be enabled to insure that the work being stitched piece after piece be stitched at eX- actly the same distance and under the same conditions, and frequently work of one kind has to be interrupted temporarily and work of another kind introduced, and when work is resumed, in attachments as ordinarily constructed, the attachment has to' be readjusted with relation to the needle forming part of the stitch-forming mechanism.

In the attachment to be hereinafter described the working parts may be removed easily and inserted quickly to resume Work, and the working parts will occupy always eX- actly the same relation and yet I have made provisions to vary the conditions of the work, as for instance, the eXact relation of the acting edge of the attachment to the needle when exigencies of the work require.

Figure 1 in plan view shows part of the work-support or bed of an ordinary sewing machine, and part of a presser-foot with my attachment securedto said support, parts of the arms carrying the attachment being shown in dotted line in their inoperative positions Fig. 2 is a side elevation of the parts shown in Fig. 1, said figure showing fabric as in position to be stitched Fig. .3 is a left the same, asrepresented in Figs. 1 and'2 Fig. 6 shows the work, Fig. 5, in section on the dotted line 5 but with the material closer together; Fig. 7 shows my attachment adjusted 'to guide a so-called California welt in boot and shoe work; Fig. 8 shows the first stages of work that may be done with the parts adjusted as in Fig. 7, and Fig. 9 shows the same opened up.

Referring to the drawing, A represents a base plate adapted to be fixed in one position on the work-support A of a sewing machine by set-screw A. The block A at its outer ends receives two stud screws B, C that serve as pivots for two arms B, C shown by full lines in their operative positions, said arms, when the parts to be described and carried thereby are not in use being capable of being turned into their inoperative posi tions 180, as shown by dotted lines at, the right hand end of Fig. 1, so that the parts carried-by said arms may be removed entirely away from the usual presser-foot A and leave the presser-foot free from any obstruction of the free movement of the material thereunder. This provision enables art of the work being done to be guided mechanically and then the parts so guiding the work to be turned readily aside, leaving the work to' be manipulated and guided by hand, and then when the guided work is to be resumed, the parts of the attachment put temporarily into their inoperative positions may be brought back into their operative positions and lie just the same with relation to the work under all conditions, so that the fabric stitched may all be stitched just alike.

The arm B is held in its operative osition by a spring catch 1", attached to the look A and engaging a recess in the underside of the part of its length to receive the shank, as b, c of attachment-carrying parts, the shank b, as I have chosen to illustrate the same being provided at its outer end with an edge gage I), while the shank c is provided with an adjustable guideway 0 for a braid, tape, piping, welt or cord 6. The shank c is surrounded by a collar 2 made adjustable thereon and held in position by a set-screw 3 contacting with the shank. These collars are adjusted on the shank in accordance with the particular stitching to be done, and each shank inserted in the hole in its arm B or C may be held in its adjusted position by a suitable set-screw 1 or 5.

Now when it is desired temporarily to discontinue the use of the attachment-carrying parts represented in the drawing, the setscrews 4 and 5 may be removed and the shanks with their adjusted collars be withdrawn from the arms B, C and the same may be done absolutely without any vibration. Whenever the shanks of the attachment-carriers are again inserted in the arms B, C to be held therein by their set-screws 4, 5 the right hand ends of the collars abut the ends of the arms and constitute positioning devices.

It is obvious that should it be desired that the guideway c occupy a different position, the collar 2 on the shank a may be adjusted thereon and again locked. The attachment parts to be described carried by the shanks b, 0 may be also put into their operative positions without removing the shanks from the arms B C by simply turning said arms for 180 about their stud-screws B, C.

The shank c has at its outer end an upright flange or head 0 provided with screw 40 threads into which enter the threaded shank of screws 0 that are extended through slots 0 in a flange c of a plate 0 carrying the guideway or portion 0 through which is led the tape, cord, or welt, the slots in said flange being of such length and width with relation to the diameter of said screws as to permit the plate and its guideway to be adjusted both vertically and horizontally on said head; vertically to accommodate for the thickness of fabric h to be moved between the under side of said plate and the worksupport, it being understood that the plate is raised as the thickness of the material h increases, and Vice versa; horizontally to enable the adjustment of the guideway toward and from the needle. The size of the slots in the flange being of both greater length and width than the diameter of the screws passing through them and being arranged parallel to each other also permits of an angular adjustment of the flanged plate on the head. In this way the guideway may be tipped to secure an easier introduction of the work, the end toward the needle being tipped down and that away from the needle being tipped up.

The shank I) having at 'its outer end the edge gage b enters a hole in the arm B and is there held by the set-screw 4 and said shank is surrounded, in addition to the collar referred to, by a sleeve that may be adjusted thereon and held in adjusted position by a set-screw 9 surrounded by a block 10 bored for the reception of the shank 12 of an auxiliary presser-foot f that may be held in its operative or inoperative positions by a set screw 14. The block 8 is held in its adjusted position on the screw 9 by a set-screw 15. The drawing in Figs. 1, 2 and 3 shows the auxiliary presser-foot in its operative position. The auxiliary presser-foot is put into its inoperative or retractedposition byloosening the set-screw 14 and sliding the auxiliary dresser-foot shank 12 to the right, and may be held in its inoperative position by tight ening the set-screw 14.

The drawing shows at A part of the usual Presser-foot of the sewing machine under which the material being stitched is fed by the usual feeding device of the sewing machine. The usual needle of the stitch-forming mechanism penetrates the material at 16.

Figs. 1 to 3 show the attachment set for guiding material h, h to have stitched therebetween by a line of stitches 17 the braid,

tape, piping or welt 6 represented in Figs. 1, 5 and 6, as when making a lapseam. After the two layers and the braid have been stitched, as shown in Figs. 1 and 2, the work is removed and the layer h is turned over to the right, see Fig. 5, and thereafter another line of stitches 18 may be inserted parallel to the line of stitching 17, thus completing a lap-seam, and leaving the edge of the braid, tape or piping exposed, as in Figs. 5. and 6. When stitching, as shown in Figs. 1 and 2, one layer passes under the plate 0 the braid or tape, through the guideway c and the other layer of material rests on the top of the guideway and on the under layer, and pasess under the presser-foot.

Fig. 7 shows the attachment adjusted for putting a welt, commonly referred to in shoe making as a California welt, in the seam closing the quarters of a shoe, the same surrounding the heel and center.

Fig. 8 shows two pieces of leather m supposed to be parts of the quarters or heel covering portions of a shoe, and n represents the California welt to be stitched therebetween.

' Fig. 9 shows the material of Fig. 8 opened out, as it will be in the shoe, leaving the edge of the welt n exposed vertically at the heel end of the shoe. To do this work the setscrew 3, holding the collar 2 on the shank b,

will be loosened and the shank will be pushedto the left to place the face of the edge gage b in such position with relation to the delivery end of the guide way 0 that the right hand edge of the California welt leaving said guideway will contact directly with the face of the edge gage and in vertical line with the edges of the two layers m, 'm of the material constituting the quarters of the shoe.

It will be obvious from the foregoing description that the attachment herein shown may be employed for a variety of work, and that the shanks shown may have connected with their heads any usual device commonly employed in sewing machines for manipulating, guiding or turning work or fabric on its way to the needle to be stitched.
